Definitions
- the invention relates to a partially aromatic copolyamide on the basis of metaxylylene diamine and hexamethylene diamine as the amine components and adipic acid and at least one further dicarboxylic acid selected from the group of aliphatic dicarboxylic acids with 7 to 10 carbon atoms as well as optional further additives.
- the multilayered packaging systems employed in these areas comprise several layers of different polymers, such as polyethylene, polypropylene, polyvinyl-chloride and -fluoride, polyvinyl alcohol, polyacrylate and other polymers, their blends and their mixtures.
- the above mentioned packaging systems are intended to protect foodstuffs, beverages and medical, chemical, biological and pharmaceutical products. In the widest sense these packaging systems include hoses, tubes, bottles, containers, packaging foils and the like.
- plastic materials used have barrier layer effects in respect to gases such as oxygen, carbon dioxide, water vapor and other gases, in addition to good working properties and good mechanical properties. It is also intended that these materials provide a barrier against flavors and fragrances or toxic and/or non-toxic gases.
- Copolyamides with metaxylylene diamine (MXDA) as components have quite often been described, among other in EP-A-411 791, EP-A-288 972, GB-A-1,575,801, JP-A-01 319531, JP-A-02 089643, JP 05 064866, JP 52-135352 with aromatic dicarboxylic acids, mainly isophthalic acid and terephthalic acid as the comonomers. Based on the required high condensation temperatures and the resulting high melt viscosities, copolyamides of this type are difficult to produce. The resulting materials have very high stiffness and brittleness.
- Copolyamides with MXDA and caprolactam such as have been described in DE-AS-18 12 018, JP 52-135353, U.S. Pat. No. 4,826,955 and WO 93/21276, must be extracted for use in the packaging field to reduce the migration of the lactam remainder. The additional extraction step lowers the profitability of the material. Nevertheless, the materials obtained do not satisfy all requirements, for example in the medical sector.
- Copolyamides made of MXDA and dimeric fatty acids have been described in EP-A-355 017 and JP-A-05 295313. Because of the long carbon chains of the fatty acid components, copolyamides of this composition show insufficient barrier properties against gases.
- MXDA metaxylylene diamine
- Copolyamide compositions of metaxylylene diamine (MXDA) and at least three further monomers and their use as a barrier layer in multilayered composites are a particular object of the invention.
- MXDA metaxylylene diamine
- HMDA hexamethylene diamine
- the monomer portions (a) to (d) add up to 100 weight-%, wherein the amine and acid components are present in approximately equi-molar portions.
- composition in accordance with the invention comprises
- the partially aromatic copolyamides in accordance with the invention can optionally contain the usual additives in accordance with the prior art, such as chain regulators (preferably amines or diamines), stabilizers, anti-foaming agents, crystallization accelerators, and the like.
- chain regulators preferably amines or diamines
- stabilizers preferably amines or diamines
- anti-foaming agents preferably crystallization accelerators, and the like.
- the production of the partially aromatic copolyamides in accordance with the present invention is performed in a known manner in accordance with the melt condensation process.
- the preferred range of the relative viscosity of the copolyamide in accordance with the invention lies between 1.6 and 2.5.
- higher as well as lower viscosities can also be produced without problems.
- Areas of use of the partially aromatic copolyamides in accordance with the present invention are found in multilayered composites for, among others, the medical area, for example as the only or an additional barrier layer in infusion and ostomy bags or in shrink wraps for meat, fish and cheese packaging or sausage skins.
- barrier layers and several further polymer layers can be used for the multilayered composites.
- Preferred further polymer layers are protective and support layers which lend the multilayered composite defined application properties. Sealing layers are required to be used in those cases where it is desired to make the multilayered composite sealable by hot sealing. Coupling agent layers can also be used advantageously.
- Preferred polymers for the protective and support layers are those consisting of polyamides, polyolefins or polyesters.
- Preferred coupling agent layers are functionalized polyolefins, i.e. polyolefins provided with functional groups.
- Sealing layers advantageously consist of low-melting polymers. So-called inomers, besides polyolefins, are preferred as sealing layers.
- the production of the multilayered composite is advantageously performed in coextrusion installations, but can also be performed by means of laminating.
- the use of the present copolyamides as a compatible blend component for mixtures with ethylene-vinyl alcohols should be mentioned as a special use, which serves to improve the deep-drawing properties and the flexibility of the ethylene-vinyl alcohol polymers and which involves a relatively small loss in the barrier effect. Blends of this type can be used for producing containers.
- the present copolyamides can also be blended with other compatible thermoplastics including polyvinyl alcohol, polyacrylates, polyolefins, polyesters, copolyesters, polyamides, copolyamides, polycarbonate and their blends or mixtures.
- copolyamides in accordance with the invention for producing mono- and multi-layered sausage skins.
- the partially aromatic copolyamide in accordance with the invention can be used in pure form or in a mixture with other polymers, for example other polyamides, preferably polyamide 6.
- copolyamides in accordance with the invention can be employed in the non-oriented or the uniaxially or biaxially oriented state for all areas of application.
- the product is delivered in the form of a strand by means of a melt pump, and the extrudate cooled in a water bath, granulated and subsequently dried.
- the oxygen and carbon dioxide permeations represented in Table 3 were measured with a gas permeability testing device in accordance with the DIN 53380 (ISO 2556) standard.
- the tensile strength of the blown films in accordance with the invention was measured in accordance with ISO 1184 traverse to the direction of the machine. In the process, values between 60 to 80 N/mm 2 were measured for the copolyamide foils in accordance with the invention.
